Can you form a grignard reagent with 4-bromoaniline 4-bromobenzoic acid or 4-bromophenol when reacted with Mg in ether and why?
A Grignard reagent cannot be formed with 4-bromobenzoic acid as it has a carboxylic acid functional group that would not react with Mg in ether to form a Grignard reagent. Both 4-bromoaniline and 4-bromophenol can form Grignard reagents in the presence of Mg in ether due to the presence of a halogen atom (bromine) in their structures, which can undergo nucleophilic substitution reactions with Mg to form Grignard reagents.
Why Grignard reagent cannot be prepared by Calcium instead of Magnissium?
The beauty of grignard reagents is their relative ease of production, in simple terms just take an alkyl halide add magnesium and stir to get RMgX which can then be reacted further. The difficulty in using calcium is that the metal itself is less reactive and calcium organometallics are relativelly unstable. Calcium organohalides are also more salt-like and are not as soluble as their Mg counterpart. This whole area is not that well understood, the mechanism of production of grignards is unclear. Certainly alkylcalcium halides are known but they are difficult to prepare and are described as extremely unrreactive.
What determine the effect of a limiting reagent on the mass of a product?
the amount of limiting reagent
How do you make yeast from ethanol?
Yeast fermentation converts sugars into ethanol. To make yeast from ethanol, you would need to reintroduce the ethanol to a suitable yeast culture medium that contains essential nutrients for yeast growth. The yeast will consume the ethanol as a carbon source and begin to multiply, adapting to grow in the ethanol environment.
How do you convert chloroform to ethanol?
Chloroform cannot be directly converted to ethanol. These two compounds have different chemical structures and cannot be interconverted without breaking down and re-synthesizing starting from a different molecule.

Why is benzene formed during Grignard reactions using phenylmagnesium bromide?
Grignard reactions must be carried out in an anhydrous environment in an anhydrous solvent (e.g. anhydrous ether). Why? Grignard reagents behave essentially as a carbanion, and are extremely reactive. Therefore they cannot be carried out while acidic hydrogens, or other positive reactive centers are present (carbonyl compounds such as acetone) in the reaction mixture because there is no way to stop the Grignard from reacting with these other compounds rather than the desired reactant. If phenylmagnesium bromide were prepared, and ANY water was present in the reaction mixture phenylmagnesium bromide would not hesitate to react with water--stealing one of its hydrogens. This hydrogen would therefore replace the attached --MgBr to form benzene.
Are you solvent?
A solvent is a substance results in a solution when it dissolves a solute. Therefore, humans are not and cannot be solvent.

Which molecule is classified as the universal solvent?
Water (H2O) is largely used as a solvent; but an universal solvent cannot exist.
What Solvent substance dissolves in saltwater?
A solvent cannot dissolve. You can dissolve a solute in a solvent, e.g. you can dissolve sugar in water - sugar is the solute, and water is the solvent. You cannot dissolve water though.

The yeast will consume the ethanol as a carbon source and begin to multiply, adapting to grow in the ethanol environment.
Does theVolume of the solvent and the volume of the solution remain the same if you add more solute to the solvent is this statement right or wrong?
This statement is incorrect. If you add a solute to a solvent the total volume is not equal to the volume of the solute plus the volume of the solvent. This seems counterintuitive but when adding two different compounds together these compounds may stack together better or worse than they would separately. This can be seen very readily when mixing pure ethanol and water. It also results in the fact that using normal distillation methods you cannot get ethanol more pure than 95%. Hope that helps
What solvent is called universal solvent?
Water is the substance that is often called the "universal solvent". However, in actuality, nonpolar substances cannot be dissolved in water.
How do you convert chloroform to ethanol?
Chloroform cannot be directly converted to ethanol. These two compounds have different chemical structures and cannot be interconverted without breaking down and re-synthesizing starting from a different molecule.
Can solute be bigger than solvent?
No, a solute cannot be bigger than a solvent. A solvent is the substance in which a solute is dissolved, and the size of the solute must be smaller than that of the solvent molecules to form a homogeneous mixture.
